By my research the first ever hat material was straw. I am not entirely sure because further down it mentioned felt but i would probably go with woven straw. Possibly in China.
felt is from animal so it is sythetic
Both the salt and the pepper are attracted to the straw because of electrical charges. When you rub the straw on the wool/felt, those electrical charges are created.
The woven cloth is referred to as baize.
In addition to team logo sports headwear, the industry's output included straw harvest hats; jungle-cloth helmets; opera hats; panamas; and hat bodies made from fur-felt, straw, and wool-felt.
There are woven fabrics, and non-woven fabrics. Examples of non-woven would be felt; tapa cloth which is made from beaten bark fibre; and papyrus which is made from beaten leaves. [Q Is paper a fabric?] Woven fabrics are much more common. Ranging from natural materials such as silk, cotton, and wool; through to nylon, polyester and so on.
The fabric is called billiard cloth or felt, but technically is not related to felt. The cloth is a woven material consisting mainly of wool and called baize. The term baize is not used by players, the surface is referred to as felt.
Felt is more flammable than cotton because it is made from compressed fibers that are not as tightly woven as cotton fibers. This looser structure allows felt to catch fire more easily and burn faster compared to cotton.
A woven fabric uses fibres that have been spun into yarn and then threaded in and out of each other as a warp and weft using a loom. Bonded fabric used the fibres loose, wet out with a polymer which when dry bonds the fibres together. Felt is a good example of a bonded fabric. As a word of caution: The term Bonded fabric is sometimes used to refer to a woven fabric that has had a coating "bonded" to it to make it waterproof. PUL (polyurethane Laminated) fabric is an example.
Cloth made of matted fibers of wool is sometimes referred to as felt.

Traditionally, black should be worn after labor day. The same is true for a cowboy hat. As a general rule, I wear black in the fall and winter and straw in the spring or summer. I also wear straw when I am working outside or in the hot sun. Black hats are felt or beaver and you wouldn't want to use it as a work hat.
